PU ndiyo chidimbu che polyurethane muChirungu, uye zita remakemikari muchiChinese ndi "polyurethane". PU dehwe iganda rakagadzirwa nepolyurethane. Inoshandiswa zvakanyanya mukushongedza mabhegi, zvipfeko, shangu, mota uye fenicha. Yave ichiwedzera kuzivikanwa nemusika. Yayo yakasiyana-siyana yekushandiswa, yakawanda yakawanda uye yakasiyana-siyana haigone kugutsikana nematehwe echinyakare echinyakare. Hunhu hwePU ganda zvakare hunosiyana, uye yakanaka PU yematehwe yakatonyanya nani pane chaiyo dehwe.
KuChina, vanhu vakajaira kudaidza dehwe rekugadzira rakagadzirwa nePU resin seyakagadzirwa PU artificial leather (PU dehwe kwenguva pfupi); dehwe rekugadzira rakagadzirwa nePU resin uye machira asiri akarukwa semidziyo yakabikwa inonzi PU synthetic leather (synthetic dehwe kwenguva pfupi). Itsika yekureva pamwe chete kumhando nhatu dziri pamusoro dzematehwe sematehwe ekugadzira.
Artificial dehwe uye ganda rekugadzira chikamu chakakosha cheindasitiri yepurasitiki uye inoshandiswa zvakanyanya mumaindasitiri akasiyana ehupfumi hwenyika. Kugadzirwa kwematehwe ekugadzira nematehwe ekugadzira ane nhoroondo yemakore anopfuura makumi matanhatu ebudiriro munyika. China yakatanga kugadzira nekugadzira dehwe rekugadzira muna 1958. Indasitiri yakagadziridzwa kare muindasitiri yepurasitiki yekuChina. Kuvandudzwa kweChina chekugadzira dehwe uye indasitiri yematehwe yekugadzira hakusi chete kukura kwemitsara yekugadzira michina yemabhizinesi ekugadzira, kubuda kwechigadzirwa kunowedzera gore negore, uye marudzi nemavara ari kuwedzera gore negore, asiwo nzira yekusimudzira indasitiri ine sangano rayo reindasitiri. , iyo ine hukama hwakakura, kuitira kuti dehwe rekugadzira reChina rive, makambani ematehwe ekugadzira, kusanganisira maindasitiri ane hukama, akaronga pamwe uye akagadzira indasitiri ine simba rakawanda.
Kutevera PVC yedehwe rekugadzira, PU synthetic dehwe yakawana budiriro yetekinoroji sechinzvimbo chakakodzera chematehwe echisikigo mushure memakore anopfuura makumi matatu ekutsvagisa nekusimudzira nenyanzvi dzesainzi uye tekinoroji.
PU yekupfekedza pamusoro pemachira yakatanga kuoneka pamusika muma1950s. Muna 1964, iyo American DuPont Company yakagadzira PU synthetic dehwe repamusoro shangu. Mushure mekunge kambani yekuJapan yatanga tambo yekugadzira ine 600,000 square metres pagore, mushure memakore anopfuura makumi maviri ekuenderera mberi kwekutsvaga nekusimudzira, PU synthetic dehwe yakakura nekukurumidza maererano nemhando yechigadzirwa, siyana, uye kubuda. Kuita kwayo kuri kuswedera pedyo nekuswedera pedyo nematehwe echisikigo, uye zvimwe zvinhu zvinotopfuura ganda rechisikigo, zvichisvika padanho rekuti zvinonetsa kusiyanisa pakati pematehwe chaiwo uye emanyepo. Inobata chinzvimbo chakakosha muhupenyu hwezuva nezuva hwevanhu.
Nhasi, Japan ndiyo inonyanya kugadzira dehwe rekugadzira. Zvigadzirwa zveKuraray, Teijin, Toray, Zhongbo nemamwe makambani zvinomiririra danho rekusimudzira nyika muma1990s. Iyo fiber uye isina-yakarukwa machira ekugadzira ari kusimukira munzira ye-ultra-fine, yakakwirira-density uye yakakwirira isina-yakarukwa mhedzisiro; kugadzirwa kwayo kwePU kuri kusimukira kwakanangana nePU dispersion uye PU mvura emulsion, uye minda yayo yekushandiswa kwechigadzirwa iri kuramba ichiwedzera, kutanga kubva shangu nemabhegi Munda wakagadzirwa kuita mamwe minda yakakosha yekushandisa senge zvipfeko, mabhora, kushongedzwa, nezvimwe. inobata zvese zvehupenyu hwevanhu zuva nezuva.
Artificial dehwe ndiro rakatanga kutsiva machira ematehwe akagadzirwa. Yakagadzirwa nePVC pamwe neplasticizers uye zvimwe zvinowedzera, calendered uye inosanganiswa pamucheka.

PU synthetic dehwe rinoshandiswa kutsiva PVC yedehwe rekugadzira, uye mutengo wayo wakakwira kupfuura PVC yematehwe ekugadzira. Maererano nekugadzirwa kwemakemikari, iri pedyo nemicheka yematehwe. Iyo haishandisi mapurasitiki kuti iwane zvinyoro zvinyoro, saka haizove yakaoma kana brittle. Iyo inewo zvakanakira mavara akapfuma uye akasiyana mapatani, uye yakachipa kupfuura machira ematehwe. Saka inogamuchirwa nevatengi.
Kune zvakare PU ine dehwe. Kazhinji, rutivi rwekumashure irworwo rwechipiri chedehwe remombe, uye chidimbu chePU resin chakaputirwa pamusoro, saka inonziwo firimu redehwe remombe. Mutengo waro wakachipa uye mwero wayo wekushandiswa wakakwira. Nekuchinja kweruzivo rwemichina, yakaitwawo kuita magiredhi akasiyana-siyana, sengedehwe remombe rinounzwa kunze kwenyika. Nekuda kweiyo yakasarudzika tekinoroji, yakagadzikana mhando, uye novel mhando, iganda repamusoro-giredhi, uye mutengo wayo uye giredhi hazvisi pasi pekutanga-layer rechokwadi rematehwe. Mabhegi ematehwe ePU uye mabhegi ematehwe echokwadi ane maitiro avo. Mabhegi ematehwe ePU ane chitarisiko chakanaka, ari nyore kuchengeta, uye akachipa, asi asingapfeki uye ari nyore kupaza. Mabhegi ematehwe chaiwo anodhura uye anonetsa kutarisira, asi anogara kwenguva refu.
Kune nzira mbiri dzekusiyanisa machira ematehwe kubva kuPVC yeganda rekugadzira uye PU synthetic leather: imwe ndeyekunyorova uye kuoma kweganda, ganda rechokwadi rakapfava uye PU yakaoma, saka PU inonyanya kushandiswa mune shangu dzematehwe; imwe ndiyo kushandiswa kwekupisa nekunyunguduka Nzira yekusiyanisa ndeyokutora chidimbu chejira ndokuchiisa pamoto. Chigadzirwa chematehwe hachizonyunguduka, asi PVC yeganda rekugadzira uye PU synthetic dehwe rinonyungudika.
Musiyano uripo pakati pePVC yematehwe ekugadzira uye PU synthetic dehwe inogona kusiyaniswa nekuinyudza mupeturu. Nzira yacho ndeyokushandisa chidimbu chiduku chejira, chiise mu peturu kwehafu yeawa, uye wochitora kunze. Kana iri PVC yeganda rekugadzira, inova yakaoma uye ine brittle. PU synthetic dehwe haizove yakaoma kana brittle.
